Screwless sparingly Ikea Lack leg extensions in 4cm steps

“foot” is 4cm Ikea Lack leg extension I needed to regain 180mm maximal print height for Prusa MINI+ below Lack table.

“foot2” is 4cm additional extension I needed for placing 4cm thick concrete slab between printer and absorber (old gym mat).

1×foot + k×foot2 extends one table leg by (k+1)*4cm length with 0≤k.

Screwless, and filament sparingly because of 41×41mm inner empty space, while remaining stable.

Both printed with PLA, 0.25mm layer height, 20% infill, no brim.
“foot” without support, “foot2” with support.

P.S:
I just needed to stack table with leg extension and found no adapter for that, so I created my own stack adapter for fitting 4cm leg extension:
